An antioxidant addition device for a 500 kV cross-linked polyethylene insulating material includes a heating hopper module and a heat-insulation conduit module. The heating hopper module includes an inlet port, a heating jacket, a material bin, and a filter screen. The heat-insulation conduit module includes a liquid metering pump, a stainless steel liquid-conduit, a heat-insulation unit, and an outlet port. The antioxidant is added into the material bin through the inlet port, heated in the material bin to a liquid phase antioxidant, filtered through the filter screen, then metered by the liquid metering pump, then passed into the stainless steel liquid-conduit, and finally discharged through the outlet port for use.
